Description

[Detailed description of the invention] This invention relates to a box blank made of thick paper such as cardboard.

Conventional boxes have crease lines on the peripheral wall corresponding to each side width, and dividing slits for the inner and outer flaps on the flat wall so that they have the same width as each side. It is not possible to assemble two or more types of boxes with different widths from punched material paper.

Therefore, it is necessary to punch out box blanks having different side widths, a large area is required for stocking the punched material paper, and inventory management becomes complicated.

The purpose of this invention is to provide a box blank whose side width can be changed from a single punched blank.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in the figure, semicircular walls 2 and 3 of the same length are connected to the left and right by sandwiching the center fold line 1 using thick paper such as cardboard, and one half circumferential wall 2 has a side wall 4 and an end from the center fold line 1 side. A fold line 2 parallel to the center fold line 1 so as to divide the wall 5 into
Furthermore, the other half-peripheral wall 3 is provided with fold lines 3' parallel to the center fold line 1 so as to divide it into end walls 6 and side walls 7 from the center fold line 1 side.

Furthermore, both end walls 5, 6 are provided with a required number of fold lines 5', 6' that allow the widths of the end walls 5, 6 to be changed.

The upper and lower edges of the semicircular walls 2, 2 have a protruding length of 5' along the fold line.
, 6' connect a lid flap 7 and a bottom flap 8 whose width is equal to the minimum width of the end walls 5, 6.

Moreover, the above-mentioned fold line 2' between the lid flap 7 and the bottom flap 8
, 5' and 3', 6' are provided with perforations 9, 10 on the extension lines of both ends thereof, which are to be separated during assembly.

In addition, in the case shown, each end wall 5, 6 has a single fold line 5', 6.
', but the number is free, and perforations 9,
No. 10 has two threads forming a pair with a narrow interval between them, and is separated and removed between the perforations.

In the figure, numeral 11 is a piece for fixing with glue or the like.

The box blank according to this invention is assembled from the above structure.In order to make a box with wide end walls as shown in Fig. 3, each perforation must be 9, the inner flap 13 and outer flap 12 are separated from the lid flap 7 and bottom flap 8, and the pair of end walls 5, 6. Bend the pair of side walls 4 and 7, and then connect the end wall 5 and side wall 7 by gluing the fixing piece 11 or the like.

Thereafter, the inner flaps 13 and outer flaps 12 of the bottom flaps 8, 8 are sequentially folded in, and after storing the item, the inner flaps 13 and outer flaps 12 of the lid flap 7 are sequentially folded in.

Next, in order to make a box with narrow end walls as shown in FIG. 2, first cut out each perforation 10, and then
6' and opposite end walls 5, 6 at the center fold line 1.
, the pair of side walls 4 and 7 are bent, and then assembled in the same manner as described above, and the inner flap 13 and outer flap 12 are folded.

As mentioned above, according to the box blank according to this invention,
Half-peripheral walls of the same length are connected to the left and right across the center fold line, and each half-peripheral wall is provided with a crease line to separate the side walls and end walls, and the required number of end walls can be changed in width. Furthermore, the lid flap and the bottom flap are connected to the upper and lower edges of the half-peripheral wall, and separation perforations are provided on the extension lines of the respective crease lines of the lid flap and the bottom flap. , the width of the end wall and inner flap can be changed by selecting the fold line and perforation.

Therefore, boxes with different widths of side walls and end walls can be assembled from a single sheet of box material paper.

In addition, since the protruding length of the lid flap and the bottom flap is not larger than the width of the end wall of the minimum width,
The outer flap never protrudes beyond the side wall.

Claims (1)

[Scope of utility model registration request] Half-circumferential walls of the same length are connected to the left and right with thick paper such as cardboard sandwiching the center fold line, and parallel to the above-mentioned center fold line so that one half-circumferential wall is divided from the center fold line side into side walls and end walls. In addition, a fold line parallel to the center fold line is provided on the other half-peripheral wall so as to divide it into an end wall and a side wall from the center fold line side, and a fold line parallel to the center fold line is provided on both end walls. A required number of fold lines are provided to change the width, and a lid flap and a bottom flap are connected to the upper and lower edges of the semi-peripheral wall, and the protruding length is not larger than the width of the end wall with the minimum width. A box blank with perforations to be separated during assembly on an extension of each of the above fold lines.
